1h all whom it may concern Be it knownthat I, ltonnur ZAHN, a subicct oi the (icrnian Emperor, residing at Plauon, in i ogtland, in the Kingdom of c Xony, Germany, have invented certain new ano. useiiul lniproven'ients in Take-Up lliochanism :tor .lilinhroideringr-Machinos, oi which the following is a specification.

lfn the hitherto known shuttle embroiderinn' machines in which opposite each shuttle two alternately operating rows of needles are pro ided which enable cinhroidering either with threads of different character or of diiierent colors, there is the drawback that the two thread take up devices must neces saiily he arranged at a considerably far distance apart from one another in order that the :noven'ients of one device he not inter- :ifcred with hythosc of the other. Because of? such construction the available space in which the machine installed and which measured in the direction from the front to the rear is disadvantageously reduced, the stand for the attendants in front of the niachine excessively removed from the fabric rendering it dillicult for the attendants to reach the latter with their hands, and furthermore the length of the part of the thread extending; from the fabric to the thread take up devices becomes uneven.

The object of this invention is to remove the drawback above referred to and is ac complished by improving the construction and arrangement oi the thread take up lovers in such a manner that the latter crossing one another permit the grou p of take up levers for one needle row during; their operation to come into the range of the other group.

liiy intention is more or less diagrammatically illustrated in the accompanying draw- 'ing in which so much of the ciuhroidering machine is shown as is necessary for the full :inderstaiuling of the construction and operatron of the new device.

In the drawing similar reference characters denote corresponding parts and Figurel is a side new of the einbroiderlng inachlne and of my new device; Fig. 2 is a front View oi the new device.

denotes the plane oil. the fabric and a and Z) denote the bars for the two needle ,QI'UHDS; These bars in well known manner are so arranged that those of one group are capable of reciprocating through the spaces between the bars of the other group. In the position shown .in l? 1 the needles secured to the bar a 03!." one group are in operative position penetrating the fabric, while the needles secured to the bar 5 of the other o'rolu arewithdrawn and out of operation.

7 and 7s denote the thread spools, c and i guide rolls for the threads, ]tis a rail listed to the machine frame having a rounded edge It, (i denotes the small thread. take up lever and o and g the large take up levers. These large take up levers or arms 0 and o are respectively secured to spindles m and a suitably borne in the machine frame and are punched a nd pressed from sheet in etal, so as to ha to hook shaped and rounded ends or heads 0 and 5/. On the sides ouch hook shaped end or head a and y is provided with lingers or projections 0. The threads for the needles or" bar (ii are each conveyed from the spool f over the guide roll 0, over the small take up leverd, then over the rounded surface of the hook shaped end 0 of the lever 0, between the fingers 0 thereof, to the needle, and the threads for the needles oi her i) are each con Keyed from the spool Ki, over the guide roll 77, the rounded edge it of the rail la, the small take up lever (Z, the rounded surface of the hook shaped head 9 of the lever 5/ between the fingers 0 thereof to the needles. Because of the peculiar shape of the lovers 0, c and g, and the a1'rangeincnts thereof shown in Fig. 2, the two groups ot lovers 0 undo are capable of ovcrlappin Without interfering with one another. w hat I claim and desire to secure by Letters Patent is: l

1. In an cinbroid-ering machine, the conihination with groups of needles for carrying dili'crent threads, of a secondary take up mechanism and groups of primary take up mechanisms, one for each group oi needles,

said primary take up uicclurnislns comprisinn spindles arranged eccentrically parallel and adjacent to one another and primary take up levers secured to said spindles, whereby the dilierent groups of primary take up mechanisms during operation without interference can overlap one another.

2. lln an enibroiderins; machine, the courhination with groups oi: needles for carrying dilierent threads, of a secondary take up nicclianlsnl and groups of primary take up mechanisms, one for each group of needles, In testimony whereof I affix my signature said primary take up mechanisms comprisin presence of two witnesses.

ing spindles arranged eeeentrically parallel ROBERT ZAHN. and ad acent to one another and prnnary take up levers secured to said spindles and Vitnesses:

each having a rounded hook-shaped head JAMES H. GoGGIN,

and lateral guide fingers on said head. M X D- ORDMANN- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. c."
